MODE OF PRODUGING RECIPROATING l,AND LATERAIi IVIOTIONS.

Specification of Letters Patent'No. 5,015, dated `March 13, 1847.

To all 'whom t may 001200711@ Be it known that I, Moens INGALLs, ofBurlington, in the county of/Bradford and State of Pennsylvania, haveinvented a new and useful Method of Producing Rectilinear ReciprocatingMovements for Reciprocating Planing-l/Iachines and for other Purposes,and that the follow-ing is a full, clear, and exact description of theprinciple or character which distinguishes itv from all other thingsbefore known, and of the manner `of making, constructing, and using thesame, reference beingrhad to the accompanying drawings, making part ofthis specication, in which- Figure -1 is a perspective view of themechanism; Fig. 2, a cross vertical section; and F ig. 3, a sectionalplan.

The same letters indicate like parts in all the figures.

The object of my invention is to produce a rectilinear reciprocatingmotion, which shall shift at each end to make the back movement in adifferent plane from 'the forward one but parallel with it. And thenature of my invention consists in having a pin or roller at each end ofthe carriage which moves back and forth to run alternately in two setsof parallel grooves which, at the ends,'run diagonally into 'each other,and provided at each of their junctions with a spring switch so that atthe end of each motion the pins shall open the switches to run into thereturn grooves, and vice versa; the carriage being provided with tworacks one above and the other below with their cogs facing each other tobe acted upon alternately by the same pinion the two racks being onopposite sides of a vertical plane, that one rack may pass by the sideof the pinion, while the other is in gear with and actuated by it, andthe pinion being so made as to have the cogs extend over its wholelength for about half its circumference and for the other half over onlythe middle third of its length, so that as the Ycarriage is shifted bythe diagonal ends of the grooves the rack that is not in gear may passover the part of the pinion that is without cogs, as it is being shiftedonto the middle sections provided with cogs around its entire peripherypreparatory to the return motion, the other rack at the same timepassing olf over the other cogless portion of the pinion when it isthrown out of gear.

In the accompanying drawings, (a) repand b", b two sets of parallelgrooves cut or otherwiseV formed therein. These grooves run diagonallyinto each other at (0,0, 0, 0,)

resents thev bed of the machine, and i and where the diagonal parts runinto yeach` other, there is a switch (d) attached to. a spring (0) to'admit of the, passage of a pin 7 (f) grooves from a carriage (g) fromone set of grooves into the other. `The carriage (g')- consists of twoend blocks' (a, m) connected together by two parallel racks (da) placedon each side of a vertical plane so that when the carriage 1s moved 1none direction'by a` pinion (713) on the horizontal vshaft (Z)that hasits bearings in two standards (m, im) the other will move by the side ofthe pinion and thus avoid the contact of the cogs. As the carriage iscarried in the direction of the arrow by the rotation of the pinionacting on the lower rack, the pins (f, f,), (only one seen in thedrawing) that project from the lower surface of the carriage run in thetwo grooves (I), 6,), and toward the end of this motion these pins runin the diagonal parts of the grooves, force open the spring switches(cl, 03,) and pass into the diagonal partl of the grooves (0, 0,)prepara tory to the return motion, and at the same time this lateralmotion disengages the lower rack from the cogs of the pinion and engagesthe upper rack, which carries the carriage back to the other end where alike operation takes vplace to reshift the carriage, &c. As the carriageis shifted by a diagonal motion at the end of its courses, the pinion(7c) is formed with the cogs extending for about one-half of itscircumference (Q), the whole length of the pinion, and on the remainingportion (0,) only one third of its length and in the middle, leaving avacant .space (p, 20,) onf each side over which the racks pass duringtheir lateral motion, so that the sectional cogs on one side shall beginto act on the rack to be engaged as they the carriage, which could notbe the case if a segmental pinion alone were used as in the methodheretofore practiced.

From the foregoing it will be perceived that the first part of myinvention may be (that 'projects downward into these` in this way asmall pinion may be used to give any desired extent of motion tojectionable on account of carriedV into eectV Without the latter, bySini'- ply using a segmental pinion Which Will first act on one rack tocarry the carriage in one direction and thenV on the other for thereturn. But for long motions, this is very obthe great diameter ofpinion required. Or instead of a segmental pinion, the first part of myinventi'on may be carried into effect bythe means of the Well knownmangle Wheel Inotion, but this is objectionable on account of complexityand liability to derangement.

Vhen this invention is to be applied for planing by a reciprocatingmotion, appropriate planing irons or bits may be attached to the endblocks of the carriage to act on theboards or plank placed on anappropriate frame Which need not be described as it makes nov part ofthe invention for which I now seek to procure Letters Patent; but itwill, be obvious that the lateral motion given to thecarriage at the endof each motion Will relieve the planes and permit them to return clearof the surface of the board.

tially as described.

2. And I also claim the method substantially as described of giving thereciprocating motions of any desired extent and greater than thecircumference of the actuating pinion byplacing the tWo racks on eachside of a plane at right angles to theaXis of the pinion, in combinationWith the pinion, having c ogs entirely around its circumference in themiddle of its length, and segments of lcogs on each side as described.
